  7. Abstract:
  8. Most of the energy consumed in the country is spent on heating and cooling of buildings. The use of various materials in building construction can have a significant impact on reducing energy waste and the cost of consuming gas and electricity. One of the ways to increase the quality and efficiency of resources, including energy saving, is to use industrial and semi-industrial materials. The purpose of this study is to compare the use of traditional, semi-industrial and industrial materials in the external wall of the building in terms of energy consumption and utilization costs, taking into account the initial cost of energy and the cost of energy during the operation period. In this regard, building information modeling in energy analysis of the exploitation period has a significant impact on the options and methods that have the least energy consumption. In fact, the process of building information is modeling using a 3D model that includes the functional and physical information of the project, at all stages of a construction project, including the period of exploitation. This process helps to provide a comprehensive analysis of the energy consumption of a building by providing geometric and functional information about the building, the material used and its various characteristics, as well as taking into account different conditions. In this research, the most commonly used methods of traditional, semi-industrial and industrial construction in Tehran were determined to compare energy consumption by conducting interviews with experienced experts and experienced builders. The use of traditional, semi-industrial and industrial methods in building external walls of the building in the country, based on a case study and using the possibilities provided by modeling of building information, was studied in terms of energy consumption. Finally, comparing the cost of each scenario with energy consumption during the construction phase, with an inflation rate of 10% and a discount rate of 15%, the current value of the scenarios was compared. The results of this study indicate that the cement block with polystyrene insulation has the lowest total cost and the least amount of energy consumed in this building. Also the clay block, which is the most common building materials according to the questionnaire due to the lowest initial cost, has the highest energy consumption
